Turkey Vulture (Cathartes aura) and Black Vulture (Coragyps atratus)
Both species of vulture were a common sight in Florida and are probably approaching superabundance at some sites. All that traffic does lead to a lot of roadkill though - which suits these carrion eaters! I'm not sure what poor mammal they were feasting on here but they were picking it clean! In Comment Box is a similar ground shot of Griffon Vultures (Gyps fulvus) from Spain for comparison.
